I can tell you’re very committed to bubble-free artwork and I want to make sure we help you get there. 🙂
Here are a few ideas:
1. It’s hard to heat up an entire large bottle of resin and have it make a significant change in the temperature. Instead, I like to measure out what I need, then put those cups of resin into a hot water bath. They will heat up warmer and quicker rather than doing the entire bottle. Of course, if you are going to do it this way, you need to be extra careful about keeping water out of your resin.
2. For me, I’ve never found that letting this formula rest for five minutes before pouring has been helpful to remove bubbles. Instead, I like to mix well, then pour it onto the surface. Will you have more bubbles this way? Yes, but now they only need to travel 1/16 to 1/8 inch up instead of maybe a couple of inches in your cup.
